What is a truss? A “truss” is formed when structural members are joined together in triangular configurations. The truss is one of the basic types of structural frames formed from structural members. A truss consists of a group of ties and struts designed and connected to form a structure that acts as a large span beam. The members usually form one or more triangles in a single plane and are arranged so the external loads are applied at the joints and therefore theoretically cause only axial tension or axial compression in the members.

    Instruction Manual 19/9/01 Dutch Gable Carport Thank you for choosing this quality carport. We strongly recommend that you read these instructions thoroughly. The carport you are building may vary from a carport previously bought or those displayed as we are constantly upgrading designs and construction methods. Please take your time to and do not rush the erection of your new carport and you will ensure a finished product of which you may be justly proud. Due to the large range of sizes and styles available, it is impossible to prepare an instruction manual for each individual size and model. The following instructions relate to a 6m wide and 6m long carport. This manual is a guide only and should be used in conjunction with the components list and engineers plans as submitted to council. Frame Components Haunch Plates – Left hand and right hand: Galvanised “Boomerang” shaped plate to join columns to roof rafters. Haunch plate must always be installed on the smooth side of the rafters. LEFT SIDE RIGHT SIDE Apex Plates: For joining rafters to form apex to roof.

  • Behavior of Statically Determinate and Indeterminate Rafters
    Bulletin No. 2018-12 First Release: August 2018 Revised: Prepared by: Dick Schmidt & Joe Miller Title: Behavior of Statically Determinate and Indeterminate Rafters Introduction Selection of a rafter system for roof framing can depend on a variety of considerations, including span requirements, opportunities to provide rafter support, load magnitudes and distributions, roof pitch and aesthetics. Each method for supporting a pair of rafters has its own set of advantages and disadvantages affecting member size as well as building performance. The objective of this bulletin, which is based upon prior published work (see Ref. [1]), is to present structural analysis equations and a comparison of various rafter systems for pitched roofs such that the implications of a specific choice are clear to the designer. Seven different rafter systems are considered: four of which are statically determinate, and three of which are indeterminate to the first degree (with a single redundant). The seven options are illustrated in Figure 1. In the figure, the symbol represents a hinged support location that is capable of resisting both vertical and horizontal displacement of the rafter at that location. The symbol represents a roller support capable of resisting only vertical displacement; horizontal displacement is not restrained in this case. The discussion is limited to uniform gravity load that is symmetric about the ridgeline. Unbalanced and nonuniform gravity loads require alternative analysis. For each system, the structural analysis results include expressions for reactions, axial force, shear force, and bending moment. We have combined these results with additional practical information to provide designers with the resources to make an appropriate selection.
